How to get the current Jenkins pipeline StepContext - jenkins

Question

I have a step in a pipeline that pulls objects from the context and uses them. However, I need to access those objects outside of the steps to feed into different steps, and the second step doesn't expose it.
stage() {
steps {
script {
def status = waitForQualityGate()
// Use the taskId
}
}
}
}
The waitForQualityGate() call only returns a boolean, so I can't access it there.
I could instead manually initialize the step, like so:
script {
def qualityGate = new WaitForQualityGateStep()
def taskId = qualityGate.getTaskId()
}
but the taskId is null. If I try to run the start methods manually on the step:
script {
def qualityGate = new WaitForQualityGateStep()
qualityGate.start().start()
def taskId = qualityGate.getTaskId()
}
It fails with the message:
java.lang.IllegalStateException: you must either pass in a StepContext to the StepExecution constructor, or have the StepExecution be created automatically
The WaitForQualityGateStep has the info I need, but I can't initialize it without having a StepContext (which is an Abstract class). How can I get one from the pipeline?

Answer 1

You can define the variable before the pipeline and in the step just set its value. This way the variable is visible across the pipeline.

Answer 2

I still have no idea how to manually get a step context to manually execute a step, but in case anyone else finds this by trying to get information out of the Sonar plugin, this is how I got the task ID that I needed.
def output = sh(script: "mvn sonar:sonar", returnStdout: true)
echo output // The capture prevents printing to console
def taskUri = output.find(~'/api/ce/task\\?id=[\\w-]*')
